using UTF-32 in NSString.

Hi,

Does anyone has information on how to use Unicode code points higher than 0xFFFF.
I need to add some supplementary multilingual plane code points to a NSString.

I can use something like this:
	NSString *aString = @"\\u0001ABCD"; //this prints fine but the [aString length] is 2

But if I have the unicode value as a int (unichar is to small)
	int Char = 0x1ABCD;
	NSString *aString = [NSString stringWithFormat:@"%C", Char]; //The resulting string contains one character with a unicode value of "ABCD".

What is the recommended way to use/create UTF-32 strings in Cocoa.

Best Regards
Georg
